The paper “A study of form factors in relativistic mixed-flux AdS_3“, with sole author Alessandro Torrielli, has been accepted for publication in the Journal of High Energy Physics. The final form preprint is available on the ArXiv (link here). The paper studies the two-particle form-factors for the relativistic limit of the integrable S-matrix of the mixed-flux AdS_3 X S^3 X T^4 string theory. Full abstract available at the link above. The screenshot below shows the beginning of section 3 where the minimal two-particle form factor is introduced.
